Case Ranges
===========

You can specify a range of consecutive values in a single `case' label,
like this:

case LOW ... HIGH:

This has the same effect as the proper number of individual `case'
labels, one for each integer value from LOW to HIGH, inclusive.

This feature is especially useful for ranges of ASCII character codes:

case 'A' ... 'Z':

*Be careful:* Write spaces around the `...', for otherwise it may be
parsed wrong when you use it with integer values. For example, write
this:

case 1 ... 5:

rather than this:

case 1...5:
